Chess engine · open showcase
FoldBot is a full legal chess engine that does not start with fixed piece prices, an opening book or learned weights. It counts what each piece can do in the position, forms an exact score from those counts and searches legal continuations. It secured the Stockfish Elo-1900 rung at 62.5%; the replay below preserves a win from the current Elo-2100 campaign.
The Elo-2100 victory
Game 8 of the current rung: FoldBot plays Black and wins in 42 plies. Step through every move of the victory, from the opening count to the final forced sequence.

Command-value lab
Choose a piece, then touch any square. Instead of looking up a fixed value, the board highlights and counts every square that piece can command from that exact position.
Evaluation without a table of values
FoldBot does not begin by declaring a queen worth nine or a rook worth five. Worth changes with position because it is the number of squares a piece can command from where it stands.
Competitive ladder
The Elo-2100 line marks Game 8—the 42-ply victory replayed above from the current tied rung.
